All issues of type above story level are not being displayed in the backlog

[Manuvimal Mohan]

All issues that are above the story level in the issue hierarchy have suddenly stopped appearing in the backlog. They are now displayed in a separate panel on the left side. How can I revert this to have them displayed in the main backlog window again?

If you are referring to epics they should have always appeared in the left-hand side (Epics Panel) and not as part of the backlog.  You can learn more about the epics panel and epics here: https://www.atlassian.com/agile/tutorials/epics#:~:text=Epics%20Panel%3A%20Go%20to%20the,that%20epic%2C%20across%20all%20sprints.

It was visible in my backlog till yesterday evening (NZT) even though the Epics panel was also available. Today morning I opened the backlog, and they have disappeared. 
By the way List and Active Sprint shows them.

I remember there was feature request ticket for this.
